Just a question

[Zeruvi]

I've just started a priest/shaman dualbox and i'd like to know what addon(s) would make the shaman follow the priests lead (target same target, pick up and hand in same quest, lightning bolt when i smite, and so on.)

try Jamba.

well that's for the follow and target same target part.

for the 'lightning bolt when i smite' thing you'll need a software to sync your keys (keyclone for example. i'm assuming you're software boxing) and lots of macros.

for some reason the addons i download never work :S only questhelper works

make sure you're using updated version of your addons (matching the wow version, for example 3.0.3 etc) as most get broken when Blizzard releases a new patch.

if the problem still persists, then i'm afraid the problem is probably between the keyboard and the chair.
Check the folder structures, make sure they are all correct. (an easy mistake is to have you addon in a double subfolder, for example "Interface>Addon>MyawesomeAddon>MyawesomeAddon>files" , when you should only have 1 MyaweomeAddon folder.)

Turned out to be the subfolder error. Thanks for the help.
